K Application filed September 22, y1923.. Serial No.l 502,336. i

To aZZ whom/it may] concern.' l l Be it known thatl l, Josnrii Benzin, acitizen of the United States, residing at Philadelphia, county ofPhiladelphia,-'and vState of Pennsylvania. have invented a new anduseful improvement in Bag-Frame Locks, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, which forml a part of this specification.

My invention relates to locks or fasteners and more particularly tolocks used on bags and the like. Y y

The object oi1 my invention is to provide a lock the parts of which maybe readily made and lreduced to a minimum number and the constructiono'i which will render the lock inexpensive in manufacture and eliicientin operation.

Having now indicated in ageneral way the nature and purpose of myinvention, l will proceed to describe a preferred embodiment thereofwith reference to the accompanying drawings, in which- Fig. 1 iS asection showing the rear view of a lock embodying my invention.

Fig. 2 is a plan view of the lock partly in section.

Figs. 8 and 4: are perspective views showing the latch and locking platein unlocked and locked positions.

Fig. 5 is a cross-section through the lock shown in Fig. l.

The casing a, the back of which is open, is provided at its ends withupwardly extending ears Z9, Z), adapted to extend through suitable slotsin the bag frame members a, and on being clinched over serve to securethe casing to the frame. v

The front wall of the casing is slotted for the passage of hasp members(Z, Z carried by the bag frame member y, and is provided with ears e, eadapted to be clinched over a top plate f, provided with a guide g, tosecure it in position. y

Slidably mounted within the casing is a latch Zz, having a slot n in itsfront edge and provided with an upwardly extending finger piece z' thetop of which is apertured for the recept-ion of a key and the oppositewalls of which are cut out as at y'. vA key post 7c extends upwardlywithin the nger piece z'. At opposite ends of the latch are downwardlyextending detents Z, Z and adjacentthe ends are boltsor hasp engagingmembers m. m suitably .bevelled towardthe iront.v The edge of the latchladjacent the rear oic the lboltsis slotted as at 0,0.

v Beneath the latch is positioned a locking plate c shorter thanthevlatch and adapted to slide transversely thereof;y rlhe locking plate isprovided adjacent its ends with de-y pressions pui?, oneor the otheriofwhich is adapted to receive one of the detents Z, Z in either ot its twonormal positions. The front edge of the locking plate `is providedcentrally with a pairof upwardlyextending ears q 'forming between them akey-engaging slotfwhile the rear edge of the plate is slotted as at r,fr. Beneath the locking plate is positioned a bowed flat springs, theends of which bear on the bottoni of thev casing, while the body bearsagainst the under side of the lock plate and maintains it in engagementwith the under side of the latch. The spring also maintains the latchvin latching position. y

A cover plate t, adapted to close the rear of the casing, being held inposition by means oi ear u. u on the end walls of the casing, is Slottedon its upper edge and provided beneath the slot with inwardly extendingiianges fu, fu. y

The lock is assembled by placing kthe spring in the casing with its endsagainst the bottom, the locking plate is placed against the under sideot the latch with the slots im in line with the slots` 0,0 and the latchand locking plate positioned above the spring. The top plate fis thenplaced on top of the latch and` the cover .plate 25 placed'in positionto close the rear ot the casing. When the hasps CZ, Z are entered inthelock, they will be engaged by the bolts m, m, and may be released bydepress-v ing the latch through the medium of the finger piece z'. It itbe desired to lock the lock, the key 7c is inserted into the inger pieceand engages in the vertical slot in flange g, so that turning of the keyeiiects a sliding ot the locking plate. `1When the locking plate ismoved7 the portions of itsp, While it is hel'd in locked position by theengagement of the other detent in its corresponding depression.

Having now fully described my invention, what l claim and desire toprotect by Letters Patent is:

l. A lock of the character described comprising a casing. a slidablelatch, a locking plate slidable relatively to the latch. and meansindependent of the latch adapted to cooperate With the locking plate toliti the latch in locking position.

2. A lock of the character described comprising a casing'. a slidab'lelatch, a locking Aplate slidable relatively to the latch, and

fixed'means adapted to cooperate with the locking plate'to tix the latchinfloclnng position.

3. i lock of the vcharacter described cornprising a casing a verticallyslidable latch7 a. transversely slidable locking plate positionedbeneath the latch, a spring bearing on the casing and on the lockingplate. and fixed means carried by the casing adapted to cooperate withthe locking' plate to tix the latch in locking position.

el.. .-i loch oia the character described comprisingr a casing avertically slidable latch,

a transversely slidable locking plate. 'cooperating means on the latchand locking` plate tending to hold the locking plate in one or the otherot two positions, and fixed means independent oitl the latch adapted tocooperate with the locking plate in one of its positions to iiX thelatch in locking position.

5. A lock of the character described co1nprising a casing open at theback, a vertically slidable latch a locking plate slidable relative to,and positioned beneath, the latch, aspring; acting between the lockingplate and the casing, a cover plate Ator the back vof the casing, andlugs carried by the cover plate adapted in one position of the locking;plate to underlie said plate and fix the latch in lockingr position.

(5. A loclr ot the character described comprising a casing, a slidablelatchg alocking plate slidable relatively to the latch, and means fixedto awall of the casing adapted in one position of the lockingplate tocoopcrate with said plate to fix the lock in lockine position. v

lntestiniony oic which invention, lf have hereunto set my handt atPhiladelphia. on this 19th day ot SepteniberplQQl.
